基于通信约束,研究了单输入单输出网络化控制系统的最优跟踪性能问题.白噪声在前向通道和反馈通道的影响也同时被考虑,得到了一些新的结论:最优跟踪性能由给定对象的不稳定极点、通信编码方法和信道白噪声决定.该结论进一步说明通信编码方法和信道白噪声是如何限制网络化控制系统跟踪能力.如果不考虑通信的影响,控制系统的最优跟踪性能就与已有的结论相同.仿真结果验证了该结论的正确性.
Based on the communication constraints, the optimal tracking performance of single input single output networked control system is studied. The influence of white noise on the forward channel and the feedback channel is also considered. Some new conclusions are obtained: the optimal tracking performance is given by The destabilizing poles of fixed objects, the method of communication coding and the decision of channel white noise.This conclusion further illustrates how the communication coding method and channel white noise limit the tracking ability of networked control systems.If the influence of communication is not considered, the optimal tracking of the control system The performance is the same as the previous one, and the simulation results verify the correctness of the conclusion.
